Question
The efficiency ratio of workers A and B is 15:17. If
both A and B collaboratively finish a task in 30 days, how long would it take for A to complete the task independently?Solution
Let the efficiency of A and B be 15 units per day and 17 units per day, respectively. So, total amount of work = (15 + 17) X 30 = 960 units Time taken by A alone to compete the whole work = 960/15 = 64 days Hence, option c.
